I am a beginner of MDK,but I am very familiar with Keil for C51 and it has been in use.So i feel kind of KEIL's product.But when I begin to use MDK,I find it's help is not useful.I even can't find easy information,E.g.:int type is in bytes,and strcmp funtion usage.I don't know what to do .Please help me.Thank you very much.
The normal way to specify the size of data types is in number of characters. Just that it is common that a "char" is one byte (8 bits) large.
strcmp() is a standard C RTL function - so what issues do you have with it? Don't you feel that the Keil implementation fulfills the requirements in the C language standard?
Thank you. But you are mistake of my means.I want to say the MDK's help is not to easy search.The two issue that I give is a example.Because in keil for 51's help, I can easy search the two issue's answer ,but in MDK's help I can't search them.

Thus, for a product, you are familiar with (in your case the C51) you are able to guess several search words and will, eventually, hit one that lead you to the information you are looking for. This, of course is not true for a product you are not familiar with.
However there should be no need for Keil to document "strcmp funtion usage" since that is standard C.

PD MDK is also 'Keil"
Thank you.I don't agree with you.In Keil for 51' help, you can get help of all kinds of help,I think mdk should do it also.But I don't know why I can't search it.
The route to go is to use Google - it will find the documentation on Keils web server.
There are a large number of threads on this forum complaining about how hard it is to locate information but it doesn't seem like Keil have put anyone on the task of cleaning up the mess.
Yes,I agree with you. You understand my means. Use google is my method too,but I think we should use the offical's document.So I post this thread.I hope someone can deal with it, then tell us.
Google finds the official documents. It's just that the search functionality on this site aren't any good. And the structure aren't good enough that you can predict where to look.
MDK should be a mature product, why .How we can tell them?
I think they know.
Just that they don't allocate any real resources for usability features. They do the minimum to maximize the profit. And it seems this has been the main goal since they got the "an ARM company" tag to the name.
Corporate decisions aren't always good for the end users. But the people who make the decisions don't always think about the users who do select different routes.
I have to agree with the OP. I also come from C51 and for someone like me who gets into major software projects only about every five years or so, it was a real help to just have to put the cursor over a library element, press F1 and get the declaration and example. I really miss that. Flicking through Kernighan/Ritchie is much slower.
My dream would be something like Intellisense (Visual Studio), especially when dealing with e.g. the ST Standard Peripheral Library. Are there any Keil competitors who have that?
Yes, I think so .I hear that IAR is a good choice, I am thinking to use it.
Well, I _think_ we are leaving. There is _no way_ we can afford those costs given the economic climate and the number of projects that are required to run in parallel to keep the business alive. Our latest product relies heavily on open source software (FreeRTOS, uIP/lwIP, FatFS).
And I forgot to mention NXP's free and fully functional USB library (device/host/OTG) at LPCware.com.
Well, I _think_ we are leaving.
And you've been saying that for how long?
As you well know, these decisions are not taken lightly. It already happened in practice - actually. Maintenance of existing products is another story.
Are you one of the MDK's developers? Your means is the MDK would not develop this question?
